In our fallen world, we have all succumbed to living our lives for our fleshly, carnal desires instead of for our spiritual calling. God calls us to move from flesh to spirit, but most of us spend our time moving in the opposite direction. The world looks so enticing. Surely just sampling what it offers wouldn’t hurt anything, right?
That strategy did not work out well for Adam and Eve, and by extension has caused us problems from the day we were born. We want the tangible delights we can taste, touch, and see. Oh, and we want them now. Our flesh is always pulling us towards the things of this world and away from our true spiritual nature.
